Tiger nut oil is a novel oil that requires more research data on its characteristics. In this study, the oil was extracted using both enzyme-aided pressing (EAP) and aqueous enzymatic extraction (AEE) methods. Using enzymes as a pre-treatment prior to mechanical pressing increased the concentration of some phenolic acids and tocopherols present in extracted oils compared to controls. High press...

This review covers the operating conditions for extracting top value-added chemicals, such as levulinic acid, lactic succinic vanillic 3-hydroxypropionic xylitol, 2,5-furandicarboxylic 5-hydroxymethyl furfural, chitosan, 2,3-butanediol, and xylo-oligosaccharides, from common lignocellulosic biomass. Operating principles of novel extraction methods, beyond pretreatments, Soxhlet extraction, ultr...

chilling is an important environmental stress that influences the yield and quality of many agricultural crops. different plants use different systems to endure this stress and minimize its effects. one of these systems is enzymatic reaction. to find out more about responses of different grapevine species and cultivars to the low temperature conditions, their enzymatic changes were evaluated in...

Abstract Green coffee processing has been hindered by low oil extraction yields from mechanical pressing and the need of using flammable hazardous solvents for defatting protein-rich cake before subsequent protein extraction. To replace use enable simultaneous lipids proteins green beans at reduced water usage, a multistage countercurrent process was scaled up 0.05 to 1.14 kg evaluated regardin...

Turmeric is the rhizomatous, herbaceous, perineal plant having many traditional and medicinal uses. Traditionally turmeric was used for spices in food system of medicine as like Ayurvedic medicine, Siddha Unani Chinese System purpose anti-microbial, antiseptic, anti-oxidant mild digestive problems.Turmeric consists wide variety phytochemicals such Demethoxycurcumin (DMC), Bis-Demethoxycurcumin ...

Conventional production of instant coffee is based on solubilisation of polysaccharides present in roasted coffee. Higher process temperatures increase the solubilisation yield, but also lead to carbohydrate degradation and formation of undesirable volatile compounds. Enzymatic hydrolysis of roasted coffee is an alternative to minimize carbohydrate degradation. In this work, products obtained f...

Solvent extraction of steam exploded lignocellulosic biomass may be a potential way to obtain antioxidative extracts and to enhance the enzymatic convertibility of the solid residue. Boiling solvent extraction (BSE) showed higher solid and phenolic yields than room temperature extraction. Solubilities of phenolics and sugars were higher in anhydrous ethanol (AE) and deionized water (DW) than in...

When harvesting corn, corn silk was discarded as waste, including the compounds isolated and identified from such flavonoids, sterols, alkaloids, polysaccharides, organic acids, volatile oils, trace elements, multivitamins. It not only pollutes environment but also wastes resources. In this paper, extraction methods commonly used for extracting flavonoids were reviewed, reagent method, enzymati...

Perilla seed oil riched in the ω-3 fatty acid especially α-linolenic acid, is associated with a beneficial role human health. In present study, Aqueous Enzymatic Extraction (AEE) of crude from seeds was investigated. The extraction parameters including enzyme type, solid-to-water ratio, pH, temperature, loading and hydrolysis time were determined by Response Surface Methodology (RSM). RSM resul...

a new method for the synthesis of water soluble polyaniline (pani) using hemin chloride (h.c) in the presence of hydrogen peroxide (h.p) is presented. hemin chloride is an effective catalyst for the oxidative polymerization of aniline in the presence of hydrogen peroxide at room temperature. the uv- vis absorption spectra of the product show a distinct absorption peak at 430 nm in ph 4.0 b...
